Sprite Warehouse shootout

The Sprite Warehouse shootout occurred in the spring of 2008 when Pegorino crime family hitman Niko Bellic was sent to a Sprite warehouse in Elizabeth, New Jersey to assassinate Ancelotti crime family underboss Charles Matteo before he could report the Pegorinos' hostile actions to The Commission in Manhattan. Bellic gunned down dozens of Russian Mafia guards before killing Ancelotti and blowing up his helicopter.

Background
In the spring of 2008, the Pegorino crime family engaged in a proxy war with the Ancelotti crime family in hopes of taking over the weak family's seat on The Commission, the governing body of the American Mafia. The Pegorinos used their Irish Mob allies and hitman Niko Bellic to perform several jobs that weakened the Ancelottis, including a false flag operation that led to them being alienated from their Albanian Mob muscle. The Pegorinos also fought against the Russian Mafia, and they stole a shipment of cocaine from the Faustin crime family in the Randalls and Wards Islands dock shootout. The Russians decided to relay their knowledge of the Pegorinos' involvement to Ancelotti underboss Charles Matteo, who decided to talk to The Commission and inform them of the Pegorinos' interloping with their affairs. This could lead to gang warfare between the Pegorinos and the Five Families of the Mafia, and Phil Bell decided to send Niko Bellic to murder Matteo before he could talk.

Shootout
Bellic and Bell drove from the Port Newark-Elizabeth Marine Terminal to the Sprite warehouse on Argus Street in Elizabeth, where Matteo was under guard from dozens of Faustin crime family mobsters. Bell told Bellic that he would "make some noise" to attract the attention of law enforcement agencies, giving him an alibi so that he would not be suspected of murdering Matteo. Bellic decided to sneak through the sewer rather than go in guns blazing, and he got the jump on the Russian mobsters inside of the warehouse. Bellic gunned down dozens of Russian mobsters as he advanced to the roof, and Matteo fled to the roof, taunting Bellic; he told him that his helicopter pilot would inform the Commission of the Pegorinos' actions in the case that he died. Bellic managed to make it to the roof, and he shot Matteo dead as he dangled from his helicopter, attempting to flee. Bellic then fired an RPG-7 rocket at the helicopter, which crashed into the warehouse, causing a large explosion. The shootout left dozens of mobsters dead, and it severely weakened the Ancelottis, who lost their only underboss.
